A remarkable new Cymbiola (Volutidae) from the Arafura Sea, Northern Territory: How many specimens are enough?

A new species of volute, Cymbiola distructa n. sp., has been collected by the Arafura Sea Prawn Fishery, northern Australia. This species can be distinguished from others in Cymbiola by its larger size, angled spire, and the outer lip form. C. distructa lacks the posteriorly inwardly recurving lobe often associated with the outer lip in adults of Cymbiola cymbiola (Gmelin, 1791) its morphologically close sister taxa. As collections as of long time citizen scientists are opened to taxonomists, many new Australian deep-water species become available for study.
